    My families ride is not riding too well. Idle is very low and the volt meter drops along with the headlights diming when i come to a stop light or stop in traffic and idle. When i give it gas the volt meter jumps up and lights brighten.. I bought a new battery hoping this would fix the prob. but no luck.
    I just did a diagnostic test and received codes 83,84, & 85.
    I understand this to be an open or shorted ECM or circuit.
    Any ideas where to start?
    Is this a symptom of a bad alternator?
    thanks
